Fox television is being cautious with its move to the digital distribution age. The company told Reuters that it is taking a more cautious approach than rival networks in making its most popular TV shows available for new distribution outlets, such as iTunes: "It's been our strategy not to try to go out first with announcements but to go out with our best strategy.

We're taking a more measured approach to what works and would not work," Fox Entertainment President Peter Liguori said during a presentation to TV critics in Pasadena. Earlier this week, both NBC and ABC agreed that making digital episodes available via iTunes had helped boost TV ratings, despite caution offered by some analysts.
